Bridges Built Before 1951
The United States has 1,333 bridges in Wisconsin built before 1951 that remain in active service.

The average design life of a bridge is 50 years, making these aging structures a significant infrastructure concern.

About Historic Bridge Data
Bridges built before 1951 are classified as historic in this database. Many were designed to 1940s standards with lower load limits and narrower lanes. While FHWA requires regular inspections of all bridges regardless of age, older structures often require more frequent monitoring and rehabilitation investment.
